Practical Aspects of Real-Time Automated Security Printing Inspection

Practical aspects implies reducing theory to practice. However, applying advanced technologies is, in fact, an expansion process not a reduction practice.This expansion process into the real world quantitatively requires orders of magnitude more complex than theoretical domain and often, qualitatively adds new dimensions to the task. Real time refers to on-line inspection of webs, sheets, or notes at speeds of 400 to 800 feet per minute. Real time refers to on-line inspection of webs, sheets, or notes at speeds of 400 to 800 feet per minute. Automated refers to the complete replacement of human inspectors. The purpose of this paper, therefore, is to examine certain aspects of real-world security printing environments as compared to various techniques in advanced vision technologies. After completing this examination of commercial and process considerations, suitable technologies will be discussed.
